WALTER SMITH, OF CHICAGO, ILLINOIS.

CLOSURE-LIFTER.

Application filed June 21,

To all whom it may concern:

Be it known that I, WALTER SMITH, a citizen of the United States, and aresident of the city of Chicago, county of Cook and State of Illinois,have invented certain new and useful Improvements in Closure-Lifters, ofwhich the following is a specification.

My invention relates to improvements in closure lifters, especiallyadapted for removing the usual card board closures of milk bottles, theobject of the invention being to provide an improved construction ofthis character, which is efficient in use and capable of economicalmanufacture.

Other object will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1, is a top plan view of a device embodying the invention,

Fig. 2 a side view of the same Fig. 3, another side view taken atsubstantially right angles to Fig. 2, and

Fig. 4, a view showing the lifter in position of use.

The preferred form of construction, as illustrated in the drawings,comprises a metallic disk 5 having a lip or lug 6 struck from andextending upwardly from substantially the central portion of said disk.The lip 6 is provided with a perforation 7 for the attachment of a cord,or the like 8 for convenience in use of the same.

The disk 5 is also provided with a central penetrating point or tang 9struck downwardly from the central portion of said disk, and situated atsubstantially the center of said disk. Cork screw points 10 are alsostruck downwardly from opposite sides of said disk, said points beingpointed and positioned at diametrically opposite points, and beingoppositely curved or inclined, as indicated in Fig. 3, to constitutecork screw points. The central point 9 is materially longer than thepoints 10 as shown.

In use, the device is applied to the ordinary card board closing plateor disk 11 of an ordinary milk bottle 12 by placing the point 9 atsubstantially the center thereof Specification of Letters Ifatent.

and pressing downwardly until said point penetrates the closure 11.Thereupon, the cork screw points 10 come into operative contact withsaid closure 11, and are engaged therewith by pressing downwardly on thedisk 5, and at the same time turning or twisting the same slightly, saidpoints operating as cork screw points to penetrate and engage theclosure 11. The closure 11 is then removed by exerting rotating pressureupon the handle 6 and at the same time pulling upwardly thereon. In thisway, the closures of ordinary milk or cream bottles may be quickly andreadily removed when desired. The device disclosed is a simple andeflicient one for the purpose, and capable of economical manufacture bybeing stamped from a solid disk of metal.

The projections 9 and 10 are preferably rounded and conically shaped,particularly the central projection 9 so as to facilitate turning of thedisk 5 relatively to the closure 11 without turning the latter in thebottle mouth.

lVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims. 7

Having described my invention, what I claim as new and desire to secureby Letters Patent is l. A device of the class described, comprising aplate having a lip struck upwardly therefrom to constitute a handle;penetrating points inclined in opposite directions struck downwardlyfrom the sides of said plate; and a penetrating central point struckdownwardly from said plate and perpendicular thereto and longer than thesaid inclined points, adapted to penetrate and anchor the device inposition to engage said inclined points, substantially as described.

point and inclined points being diametrilvitnessest cally disposed onsaid plate, substantially as JosHUA R. H. Porm's, described. B. G.RICHARDS.
